The Thinnest Sightline
Rest assured, the appearance of our aluminium windows suffers no compromise when being designed.
We offer two windows sizes, the OW-70 and the Ow-80. The difference between them is the sightline – the OW-70 range offers more natural light and less window profile as it has the thinnest sightline.
If you are looking for a larger window and more customisation and configurations, then we recommend the OW-80.
Both window ranges offer a guarantee of up to 20 years and a range of RAL colours and popular colours available on a faster lead time.
Cherwell will prepare your windows to your specification, including dual colour windows. Simply provide us with the RAL colour, and your windows will be blend seamlessly with your home.
Modern, contemporary and state of the art designs will allow your home to exude style and class which will be second to none.

Origin Aluminium Windows Benefits
Warmth and Security
The subtle strength of aluminium provides your home with warmth and security, whilst supporting the current popular designs of vast window spaces and areas.
Using 28mm sealed units and polyamide thermal break technology, Cherwell ensures that all windows conform to the Building Regulation requirements. This applies to new build, replacement and refurbishment projects.
We recommend you visit one of our showrooms in Banbury, Beaconsfield or Henley on Thames to see this highly distinctive design. We guarantee you’ll fall in love with its superb looks, sleek appearance, and style.
Not only does this make for a highly contemporary looking window, but one that is equally at home in older and traditional properties. This means a window product that has a design to meet any type of home and window requirement.
Virtually maintenance-free and energy-efficient
Our premium grade aluminium combines strength and robustness with a lightweight structure – producing a product that won’t warp, flex or corrode in variable weather conditions.
Combining beauty and brawn – All of our windows are PAS 24 certified
The OW-80 window range feature Yale’s renowned Encloser system, which offers the highest level of security by engaging cylindrical cams into the window keeps.
The OW-70 window range offers the Nemesis multipoint lock, which is fitted to accurately align with the keeps and the cams are manufactured to be finely adjusted if necessary.

With so many colours, how do you choose one?
There are over 150 colours in the Origin colour palette, making it easy to find the right one for you. With the option of dual colour too, you can choose to have different colours on the inside and outside of the window.
Our aluminium windows are finished with durable, scratch-resistant powder coating making them almost maintenance-free and smooth to the touch.
Together with the 20-year guarantee, our windows will make your home look and feel modern and give you peace of mind.
Finishes
If you’re needing a window quickly, choose a colour from one of our popular colours range and you can have it in a couple of days.
Realistic woodgrain
You aren’t just restricted to flat colours with our Origin range, you can also choose our realistic woodgrain finish. If you’re looking to match your new windows with existing ones or replace them all but keep the traditional look, this finish is perfect for you.
Made in Britain
We want you to feel safe and secure in your home, which is why Origin has taken every step to ensure that our windows satisfy and surpass current building regulations. This includes factors such as emergency exits, restricted opening and marine-based dwellings.
Extra ventilation can be added inside the sash through the installation of trickle vents, and side hung windows can be designed to serve as emergency exits that comply with British Building Regulations.
Can you handle the choice?
Our Origin handles come in an array of colours to complement the windows. Designed for beauty and built to last, our handles offer functionality, security and can be colour coordinated to the frame.
To find out which handles are available specifically for OW-70 and OW-80, please read our comparison table.
